End of Life Disposal

The Freedom XC Inverter Charger is designed with environmental
awareness and sustainability in mind. At the end of its useful life,
the Freedom XC can be decommissioned and disassembled.
Components which can be recycled must be recycled and those
that cannot be recycled must be disposed of according to local,
regional, or national environmental regulations.

Many of the electrical components used in the Freedom XC are
made of recyclable material like steel, copper, aluminum, and
other alloys. These materials can be auctioned off to traditional
scrap metal recycling companies who resell reusable scraps.

Electronic equipment such as the circuit boards, connectors, and
fuses can be broken down and recycled by specialized recycling
companies whose goal is to avoid having these components end
up in the landfill.

1 INTRODUCTION

The Freedom XC Inverter Charger is designed with integrated
inverting and charging functions and power management features
suitable for Recreational, Commercial and Fleet Vehicle, or
Marine installations.

Please read this section to familiarize yourself with the main
performance and protection features of the Freedom XC. This
section includes:

Over temperature
Alarm and

Shutdown

During Battery Mode, the Freedom XC
automatically alerts you if it is overheating
and approaching the over-temperature
shutdown limit. The Freedom XC

automatically shuts down when the limit is
exceeded. See Troubleshooting Reference on
page 78 for precautions.

Dead Battery Another feature of the Freedom XC is dead
Charging battery charging. This is the ability to
recharge batteries, even if the battery voltage
has reached 0 VDC.

Ignition Control The Freedom XC provides two userselectable options for ignition control:

n Ignition Auto-on : The Freedom XC
can automatically turn the
inverter/charger on and off in tandem
with the vehicle's ignition circuit or a
manually operated remote switch.

n Ignition Lockout : The Freedom XC
features the ability to inhibit the
inverter/charger from operating in the
absence of a voltage signal from a
vehicle's ignition circuit. This is
particularly useful if the inverter/charger
is required to operate only when a
vehicle's engine is running.

Built-in Charge For the inverter/charger to perform at the
Formulas highest level, the batteries must be charged
correctly. The Freedom XC has optimized
algorithms for flooded, gel, AGM, custom,
and lithium iron phosphate [LFP (or LiFePO 4 )]
Xantrex Batteries.

Manual Over a period of time, the cells in a flooded
Equalization battery can develop uneven chemical states.
This can result in a weak (undercharged) cell
which, in turn, can reduce the overall capacity
of the battery. To improve the life and
performance of a non-sealed, flooded battery,
the Freedom XC multi-stage charging cycle
includes a manual equalize mode that can be
used, if recommended by the battery
manufacturer.

Configurable AC
Output Frequency
and Voltage

The Freedom XC is factory set to 60 Hz AC
output frequency and 120 V AC output
voltage. It can be configured to 50 Hz for use
in regions outside the USA and Canada. The
AC voltage setting can also be configured to
either of three settings: 108, 110, or 120 volts.

4 Freedom XC Owner's Guide

Materials List

Load The Freedom XC has a built-in 30A transfer
Management relay (Freedom XC 1000) that connects the
inverter/charger output or AC input from the
AC generator to the loads. Because the usual
AC power sources such as small generators
often have limited current availability, having
the capability to manage your AC loads is
extremely valuable. The Freedom XC
provides a number of features to facilitate
this.

n The charger is power factor corrected to
use AC current as efficiently as
possible. Minimizing the AC current
used by the charger means more current
is available for your AC loads.

n The Freedom XC has a power share
feature which prioritizes your AC loads
by reducing the charge current and
maintaining the total input current to
less than the breaker setting.

975-0784-01-01 15

Basic Installation Procedures

16 Freedom XC Owner's Guide

AC Shore Power

A source of 120 volts AC 60Hz sine wave alternating current
provides energy to pass power through to AC loads. This source
is usually the utility grid (power company) or an AC generator. An
automatic or manual AC source selector switch can be used to
switch between the multiple sources of shore power to the
Freedom XC system.

The AC source feeding the Freedom XC must have the neutral
conductor bonded to ground. When the inverter/charger passes
shore power through, it will lift its internal bonding relay on the
output and will rely on the input neutral being bonded in order to
ensure that the power delivered to a sub panel is properly bonded.
See AC Output Neutral Bonding on page 19 for more information
on bonding relay operation.

NOTE : Throughout this guide, the term “shore power” refers to AC
input power from a utility grid, generator, or other AC source.

AC Disconnect and Over-Current Protection Device

Most safety requirements and electrical codes require the
Freedom XC’s AC and DC inputs and outputs to be provided with
over-current protection (such as branch-rated circuit breakers or
fuses) and disconnect devices.

Basic Installation Procedures

AC Input The branch-rated circuit breaker or fuse (connected
through hard wiring) that is used to supply the
Freedom XC must be rated at no more than 30A
and must be approved for use on 120 volts AC
branch circuits. The wire used between the breaker
and the Freedom XC input must be sized
adequately to carry current up to the rating of the
input breaker and in accordance with the electrical
codes or regulations applicable to your installation.

AC Output The branch-rated circuit breaker or fuse must be
rated at no more than the rating of the input breaker
in the installation and must be approved for use on
120 volts AC branch circuits. The wire used
between the Freedom XC and the AC output
breaker must be of adequate size to match the AC
input circuit breaker’s rating. The wiring from each
AC output breaker to each of the loads must be
adequately sized to carry the current rating of the
individual AC output breaker.

975-0784-01-01 17

Basic Installation Procedures

Disconnect Each system requires a method of disconnecting
Devices the AC circuits. If the over-current protection
devices are circuit breakers, they will also serve as
the disconnects. If fuses are used, separate AC
disconnect switches will be needed ahead of the

fuses. These will have to be a branch circuit rated
for 120 volts AC and have an appropriate current
rating.

AC Distribution Panels

Most systems incorporate distribution centers both ahead of the
Freedom XC (the AC source panel) and between the Freedom XC
and the loads (the AC load panel). An AC source panel includes a
main circuit breaker, which serves as over-current protection and
as a disconnect for the AC shore power supply line. Additional
circuit breakers serve individual circuits, one of which serves the
Freedom XC. The AC load panel can incorporate an AC output
circuit breaker and breakers for individual load circuits.

AC Cabling

AC cabling includes all the wires and connectors between the AC
source and the Freedom XC, as well as all AC cabling between
the Freedom XC and the AC output panels, circuit breakers, and
loads. The type and size of the wiring varies with the installation
and load. For example, in high vibration environments, such as
marine or RV applications, wire nuts may not be acceptable, so
crimp splices would be required. In other applications, flexible
multiple-strand wire may be required. Installation codes usually
specify solid or stranded, overall size of the conductors, and type
and temperature rating of the insulation around the wire.

18 Freedom XC Owner's Guide

AC breakers and fuses must be sized to adequately protect the
wiring that is installed on the input and output AC circuits of the
Freedom XC. All breakers and wiring must be sized and
connected in accordance with the electrical codes or regulations
applicable to your installation. Table 4 gives some examples of
wiring sizes based on the U.S. National Electrical Code and the
Canadian Electrical Code. These examples are based on using a
two-conductor-plus-ground copper cable rated at 60 ° C, and
assuming an ambient temperature of up to 30 ° C. Ensure that your
breakers and fuses have suitable temperature ratings for your
wiring. Other codes and regulations may also be applicable to your
installation.

Table 4 Required AC Wire Size vs Breaker Rating

Basic Installation Procedures

AC Output Neutral Bonding

The neutral conductor of the Freedom XC’s AC output circuit (that
is, AC Output Neutral) is automatically connected to the safety
ground during inverter operation. When AC utility power is present
this connection is not present, so that the utility neutral (that is,
AC Input Neutral) is only connected to utility ground at your
source. This conforms to the National Electrical Code (NEC),
which requires that separately derived AC sources (such as
inverters and generators) have their neutral conductors tied to
ground in the same way that the neutral conductor from the utility
is tied to ground in only one place. Check the regulations for your
specific application to ensure that the installation will comply with
the necessary requirements. In other words, the AC Input Neutral
ground bonding and Output Neutral ground bonding must be
isolated from each other.

AC Grounding

As per UL458 SA29.5, for all permanently connected marine
inverters: The Freedom XC should be connected to a grounded,
metal, permanent wiring system. Also, make sure that an AC
ground wire is connected to the AC ground terminal on the unit. Do
not just connect the line and neutral wires.

All connections to the unit shall comply with all regulations,
directives, local codes and ordinances.

975-0784-01-01 19

Basic Installation Procedures

Ground Fault Circuit Interrupters (GFCIs)

A GFCI is a device that de-energizes a circuit when a current to
ground exceeds a specified value that is less than that required to
blow the circuit breaker. GFCIs are intended to protect people
from electric shocks and are usually required in wet or damp
locations.

Installations in marine and recreational vehicles require GFCI
protection of branch circuits connected to the AC output of the
Freedom XC.

The following GFCI receptacle will work correctly with the
Freedom XC in the inverter/charger’s AC output distribution wiring
system.

Table 5 GFCI

Alternatively, the Freedom XC GFCI kit (sold separately; order
PN: 808-9817) option is also available to use with the Freedom
XC inverter unit. See item 11 on page 9 .

DC Cabling

This includes all the cables and connectors between the batteries,
the DC disconnect and over-current protection device, and the
Freedom XC. Most mobile installations require multi-strand
insulated copper cables for flexibility and durability in high
vibration environments and require disconnects and over-current
devices. Electrical wiring sizes in North America are indicated by
AWG notation. In other parts of the world, the metric system is
used. Under the AWG standard, a larger gauge number indicates
a smaller wire diameter. Wire size is usually marked on the larger
sized cables. Table 6 specifies the minimum recommended DC
cable size and maximum fuse size for the Freedom XC. The DC
cables must be stranded, copper, and must be rated 90 °C
minimum. The cables should be terminated with lugs that fit the
5
DC stud terminals snugly ( / 16 " hole size) and properly torqued
according to manufacturer-specified torque setting.

20 Freedom XC Owner's Guide

Table 6 Required Cable Sizes

IMPORTANT : Using the correct cable size is critical to achieving
the rated performance of the Freedom XC unit. When starting a
heavy load the Freedom XC can draw current surges from the
battery of up to 400A. If the DC wiring is too small the voltage drop
from this surge will result in a voltage at the Freedom XC
terminals that is too low for the Freedom XC to operate correctly.
The Freedom XC may appear to operate correctly with smaller
cables until a heavy load such as a microwave or refrigerator
attempts to start - then the unit may work correctly sometimes
and not work correctly other times.

Basic Installation Procedures

DC Disconnects and Over-Current Devices

The DC circuit from the battery to the Freedom XC must be
equipped with a disconnect and over-current device. This usually
consists of a circuit breaker, a “fused-disconnect”, or a separate
fuse and DC disconnect. Do not confuse AC circuit breakers
with DC circuit breakers. They are not interchangeable. The
rating of the fuse or breaker must be matched to the size of cables
used in accordance with the applicable installation codes. The
breaker or disconnect and fuse should be located as close as

possible to the battery, in the positive cable. Applicable codes
may limit how far the protection can be from the battery.

Batteries

The Freedom XC uses 12-volt battery banks. Every Freedom XC
system is recommended to have a deep-cycle battery (house) or
group of batteries with a total capacity of 100 Ah or more which
provides the DC current that the Freedom XC converts to AC.

Marine

Use stranded copper wire that is bare or has insulation rated
minimum 105 °C, and connect it between the Chassis Ground lug
and the boat’s DC grounding bus or engine negative bus. For the
Freedom XC 1000, use a wire of gauge 3AWG minimum. For the
Freedom XC 2000, use a wire of gauge 1/0AWG minimum. See
regulatory references below.

Step 7: Connecting to Port(s) on the Freedom XC

Connecting to ACC Signal

The Freedom XC can be wired to inhibit inverter operation in the
absence of a vehicle’s (or vessel's) ignition control signal. This
feature can avoid unnecessary battery drain that would otherwise
occur if the inverter was operated without a charging source such
as the vehicle alternator.

Regulatory

references

For DC voltage systems 60 VDC or less in an RV installation, an 8AWG copper
bonding conductor would be acceptable for the inverter/charger enclosure ground
bonding only per UL458 §63.6; §30.10 standard [≤150 mV @ 30A connection, per
§63.9; §63.10] and per ANSI/RVIA LV code §2-5.1 Bonding Voltage Converter
Enclosures. The "house" battery system must, however, be ground bonded per
ANSI/RVIA LV code §2-4 Auxiliary Battery Grounding; and
For DC voltage systems 60 VDC or less in a marine installation, [UL458 §SA7.2]
a DC Grounding conductor shall not be smaller than one size under that required
for current carrying conductors supplying the device per ABYC E-11 §11.16.2 but
not less than 8AWG [USGC 46 CFR §111.05-31].

Testing in Battery Mode

To test the Freedom XC:

1. For hard wired installations, ensure shore power is not
   present.

2. Press the Power button to turn the inverter/charger on.
   The green LED indicating Battery mode (Inverter mode)
   turns on and the LCD screen displays the BATT. MODE
   icon.

3. Connect a test load, such as a lamp within the power rating
   of the inverter/charger into the Freedom XC GFCI or an AC
   outlet hard wired to the Freedom XC.

4. Turn the lamp on to verify that it operates.
   If the lamp operates, your installation is successful. If your
   installation has AC input and output hard wired to the Freedom
   XC, proceed to Testing in Grid Mode .

If the status LED on the display panel glows red, see the
Troubleshooting chapter.

Testing in Grid Mode

To test the Freedom XC:

n With the test load from the previous test still connected and
operating, connect the shore power source.

n The Freedom XC transfers the test load to shore power. The
green LED indicating grid mode turns on and the LCD screen
displays the AC MODE icon.

n If the test load operates, your installation is successful.

Basic Installation Procedures

NOTE : If the Power button on the Freedom XC is turned ON, the
Freedom XC will automatically supply the appliances with inverter
power if the shore power source fails or becomes disconnected.

If the Power button on the Freedom XC is turned ON and shore
power voltage is too low (less than 90 volts AC), the unit will
transfer to inverter power to continue running your appliances.

NOTE : Whether or not the Power button is turned ON, shore
power will pass through the Freedom XC to the output when shore
power is within normal operating range. The unit also starts
charging the battery after the transfer to grid mode.

NOTE : In the event of low or no battery voltage, shore power will
pass through the Freedom XC to the output even when shore
power is outside the normal operating range.

Power Save Timer

The Power Save Timer is an adjustable countdown timer from 1 to
25 h (25 h is the default) that automatically shuts down inverter
operation to reduce battery discharge and preserve battery life.
During continuous inverter operation, the countdown is initiated
when power from the AC load drops to less than approximately
50 W and remains below this level. After reaching the end of the
countdown timer the inverter/charger automatically shuts down.

To change the countdown timer, see Settings on page 1 .

Power Save Mode

By enabling the power save mode, also called load sensing, the
inverter/charger can automatically go to power save mode by
sending short pulses to further reduce the battery discharge.
Power save mode ends when a load greater than 25 W is
connected.

NOTE : Certain types of loads can cause power save mode to
work unexpectedly. These types of loads are described in
Problem Loads on page 83 .

Operating in Battery Mode

Checking Battery Status

During inverter operation (in battery mode), you can check the
battery status by observing the battery capacity indicator on the
LCD screen. The battery voltage appears in the left side of LCD

screen.

The normal operating battery voltage range is between 11 and
15 volts.

Checking Output Power

When the inverter/charger is in operation (in battery mode), you
can check how much power (displayed in kW) the Freedom XC is
supplying to the connected loads by observing the load capacity
indicator on the LCD screen. The battery discharge amperage
appears in the right side of the LCD screen.

Operating Several Loads at Once

If you are going to operate several loads from the Freedom XC,
turn them on one at a time after you have turned the
inverter/charger on.

Turning loads on separately helps to ensure that the
inverter/charger does not have to deliver the starting current for all
the loads at once, and will help prevent an overload shutdown.

Turning the Audible Alarm ON or OFF

The Freedom XC’s audible alarm can be muted. See Adjusting
Settings in Configuration Mode on page 51 .

Any warnings such as error or fault conditions or imminent
shutdown are both displayed on the LCD screen and sounded on
the alarm speakers. See To manually reset the alarm: on page 60 .

Audible alarm for warning: The unit beeps once when a warning
condition is detected.

Audible alarm for error: The unit beeps once every 5 s for 1 min.

To mute the alarm:

n Press any one of the three function buttons.
The alarm is automatically muted after 1 min. But the error code
continues to be displayed until the error is cleared.

To manually reset the alarm:
1. Press the Power button to turn it to Standby (from a down
position to up) and press again to turn it On to reset an active
alarm and clear the error.

2. If the Inverter Ignition Control is set to auto-on, toggle the
   ignition signal to clear the alarm and error.
3. Toggle the AC input power to force the transition between
   grid mode and battery mode. This action clears the alarm
   and error.

Operating in Grid Mode

Battery Charger Functions

When AC power is available, the Freedom XC can operate as a
12-VZ battery charger. Different battery types and chemistries
require different charging voltage levels. Not charging batteries at
the required levels can shorten battery life or damage the
batteries. The Freedom XC is configured at the factory to work
with the battery types recommended for inverter applications. If
the default settings do not work for your specific installation, you
can adjust the charge stage settings (as recommended by the
battery manufacturer) on the Custom (Battery) Settings menu
(see Custom Battery Settings Menu on page 65 ).

NOTE : This information is provided for guidance only. Variations
in battery chemistry and site-specific environmental
considerations mean that you should consult your system
designer or battery manufacturer for specific recommendations for
appropriate battery voltage and current settings.

Operating in Grid Mode

Battery Types

The Freedom XC Inverter Charger charges flooded (or wet) leadacid, Gel, AGM (absorbed glass mat), custom, and lithium iron
phosphate (LFP) Xantrex batteries.

n Flooded (or wet) batteries have removable battery caps for
refilling with distilled water and testing the electrolyte.
NOTE : Add distilled water in each cell until battery acid
reaches the level specified by the battery manufacturer. This
helps purge excessive gas from cells. Do not overfill. For a
battery without cell caps, carefully follow the battery
manufacturer’s recharging instructions.

n Gel batteries have the electrolyte in the form of a gel rather
than a liquid and do not require topping up. Gel batteries are
sealed and the battery caps are not removable.

n AGM (Absorbed Glass Mat) batteries are similar to gel
batteries except that the electrolyte is absorbed into a
fiberglass matting.

n Custom battery is configured by the dealer, factory, or
service center for battery types other than those listed
above.

n Lithium iron phosphate (LFP) must only be selected with a
lithium-ion Xantrex Battery with BMS. Other lithium-ion
batteries with a certified / listed BMS may be considered a
Custom battery.

Operating in Grid Mode

62 Freedom XC Owner's Guide

Bulk Stage
Bulk charge is the first stage in the charging process and provides
the batteries with a controlled, constant current. Once the battery
voltage rises to the absorption voltage threshold, the charger
switches to the absorption stage.
Absorption Stage
During the absorption stage, the Freedom XC begins operating in
constant voltage mode and the current falls gradually as the amp
hours are returned to the battery.

Table 11 Preset Absorption Voltage Settings

The Freedom XC transitions to the float stage if either one of the
following two conditions are met:

n The charge current allowed by the batteries falls below the
exit current threshold, which is equal to 10% of the
programmed charge current and a minimum of 2A.

n The Freedom XC has been in absorption for the
programmed maximum absorption time limit. The default is
6 h.

Operating in Grid Mode

NOTE : If there are DC loads on the batteries, the charger’s
current may never decrease to a level to initiate the next stage of
charging. In this case, the charger would stay in absorption until
the Absorb Time setting is reached.
Float Stage
Float charge maintains the batteries slightly above the self
discharge voltage of the batteries. The charge current in float is
the current necessary to maintain the batteries at the Float
Voltage setting, limited only by the inverter/charger's capability or
other settings that limit the inverter/charger's maximum charge
rate. Float charging reduces battery gassing, minimizes watering
requirements (for flooded batteries), and makes sure the batteries
are in a constant state of readiness. The charger automatically
switches to the float stage after the batteries have received a bulk
and absorption charge (see Float Stage ). The batteries are
maintained at the default float voltage level for the selected
battery type or the voltage selected under Float Voltage on the
Custom Battery Settings menu.

Table 12 Preset Float Voltage Settings

975-0784-01-01 63

Operating in Grid Mode

NOTE : The battery voltage can increase above the float voltage
when using an external charging device such as PV arrays, wind
turbines, and micro-hydro generators. Be sure to include
appropriate charge management equipment with all external DC

sources.

Equalize Charging

Many battery manufacturers recommend periodic equalize
charging to counter cell charge imbalance and capacity-robbing
electrolyte stratification. Equalizing helps to improve battery
performance and lifespan by encouraging more of the battery
material to become active.

Battery equalization is a controlled overcharging method that
mixes up stratified electrolyte and reactivates unused areas of the
plate material. Periodic equalizing can help to regularly restore
batteries to a full and healthy state of charge.

Consult the battery manufacturer's recommendation for equalize
charging settings. Sealed batteries should never be equalized.
Consult the battery manufacturer for optimal charging procedures
when using Lithium and Sealed batteries.

When Equalization is enabled, the battery is charged from bulk to
absorption, and then to the equalize phase. The Freedom XC will
transition from the absorption phase to equalize at an equalize
current set to 10 A.

After absorption, this constant current charge will continue until
the voltage has increased to 16 volts DC.

Equalization duration is fixed at one hour.

Operating During Transition Between Grid Mode and Battery Mode

975-0784-01-01 65

Operating Limits

Transitioning from Grid Mode to Battery Mode

When the unit is operating in grid mode and shore power is lost,
the Freedom XC has less than 20 milliseconds (default) to switch
to operating in battery mode (if the Power button is pressed in the
On position) and starts drawing power from the battery.

The operating mode indicator will change to Battery Mode and the
green Status LED for Battery Mode will light up.

However, if the Power button is in Standby, this transition does
not happen and the display panel turns off.

Transitioning from Battery Mode to Grid Mode

When the unit is operating in Battery Mode and shore power
becomes available, the Freedom XC begins a 20-second
countdown to verify the stability of the shore power. If shore
power remains stable for a 20-second countdown, at the end of
the countdown, the Freedom XC will switch to shore power mode
within 20 milliseconds and start drawing power from the AC

source.

The operating mode indicator will change to grid mode and the
green Status LED for grid mode will light up.

Overload Conditions

There are two kinds of overload conditions – an overload warning
and an overload shutdown.

Overload When the Freedom XC’s AC load is approximately 100 W
Warning below the overload shutdown limit of rated watts, the
audible alarm beeps once and the LCD screen shows a
warning code E06.

Overload When the Freedom XC’s AC load increases to near

Shutdown ~1100 W (Freedom XC 1000) and ~2100 W (Freedom
XC 2000), the audible alarm beeps every five seconds

for one minute and the LCD screen shows a error code

E03. The Status LED turns solid RED.

Operating in Grid Mode

High Surge Loads

Some induction motors used in freezers, pumps, and other motoroperated equipment require high surge currents to start. The
Freedom XC may not be able to start some of these motors even
though their rated steady state current draw is within the
inverter/charger’s limits. The unit will shut down and indicate an
overload shutdown.

Over-temperature Conditions

During inverter operation, when the Freedom XC’s internal
temperature starts to approach its preset shutdown limit, the
display will show error code E07. If the over-temperature condition
persists, the display will show error code E04. The Status LED
turns solid RED and the inverter/charger will shut down to prevent
damage to the inverter/charger and protect the battery from being
over-discharged.

Inverter Applications

Inverter Applications

The Freedom XC performs differently depending on the AC loads
connected to it. If you are having problems with any of your loads,
read this section.

Resistive Loads

These are the loads that the inverter/charger finds the simplest
and most efficient to drive. Voltage and current are in phase (that
is, in step with one another). Resistive loads usually generate
heat in order to accomplish their tasks. Toasters, coffee pots, and
heater elements are typical resistive loads. It is usually
impractical to run larger resistive loads—such as electric stoves
and water heaters—from an inverter due to their high current
requirements. Even though the inverter/charger can most likely
accommodate the load, the size of battery bank required would be
impractical if the load is to be run for long periods.

Motor Loads

Induction motors (that is, motors without brushes) require two to
six times their running current on start up. The most demanding
are those that start under load, for example, compressors and
pumps. Of the capacitor start motors (typical in drill presses, band
saws, etc.), the largest you can expect to run is ½ hp (the transfer
relays are rated at 2 hp). Universal motors are generally easier to
start. Since motor characteristics vary, only testing will determine
whether a specific load can be started and how long it can be run.

If a motor fails to start within a few seconds or loses power after
running for a time, it should be turned off. When the
inverter/charger attempts to start a load that is greater than it can
handle, it will turn itself off after a few seconds.

Long Transfer Times

The Freedom XC may take a long time (~ 0.1–0.2 s) to transfer to
Battery Mode when shore power is cut off while powering a motor
load. Motor loads typically “freewheel” when power is removed (for
example, a grinder) and causes a longer transfer time. The longer
transition from shore power to inverter power may cause
connected computers or other sensitive equipment to operate
incorrectly. To avoid this effect, do not connect motor loads
together with sensitive equipment to the inverter/charger for

power.

82 Freedom XC Owner's Guide

Problem Loads

Very Small Loads If the power consumed by a device is less
than the 25-watt threshold of the power save
mode circuitry, and power save mode is
enabled, the Freedom XC will not run. Most
likely the solution will be to disable power
save mode.

Fluorescent Some devices cannot be detected when load
Lights and Power sensing. Small fluorescent lights are the
Supplies most common example. Some computers

and sophisticated electronics have power
supplies that do not present a load until line
voltage is available. When this occurs, each
unit waits for the other to begin. To drive
these loads, either a small companion load
like a light bulb rated for more than 25 W
must be used to bring the Freedom XC out of
power save mode, or the Freedom XC may
be programmed to remain on by disabling
power save mode.
Clocks You may notice that your clocks are not
accurate. Some of the clocks on your
appliances may reset when the Freedom XC
is in power save mode.

Inverter Applications

When the Freedom XC is in power save mode, it may fail to start
some loads even though the rated wattage on the load is more
than 25 W. If these kinds of loads are in the system, follow the
suggestions given to eliminate the problem.

If the problem loads cannot be eliminated, there are two workaround solutions:

1. Disable power save mode from Settings on page 53,
   causing the Freedom XC to always remain at full output
   voltage.
2. Use a search-friendly companion load whose only purpose
   is to be switched on to wake up the Freedom XC to power
   the load that is unable to bring the Freedom XC out of power
   save mode.

NOTES :

n Power save mode, by function, cannot work with clocks
and timers or devices that need power 24 hours a day.
Examples of devices with timers include cable TV boxes,
coffee makers with brew timers, refrigerators, and freezers
with defrost timers. Examples of devices that need power
24 hours a day include telephone answering machines,
alarm systems, motion detection lights, and some
thermostats.

n When the Freedom XC is load sensing the output for loads,
lights that have a wattage lower than 25-watt threshold,
may flash momentarily.
